Abstract:
The difficulty to discriminate speech in noise (SND) is a common auditory symptom, which affects both hearing impaired individuals and those with hearing within normal parameters. However, in our region this difficulty is evaluated only in subjects who are prescribed with hearing aids.
The objective was to describe the SND in young university students with normal hearing from Córdoba between 2020 and 2021.
A descriptive cross-sectional correlational study was carried out. Thirty-three students between the ages of 20 and 30 with normal audiometry participated. Those who presented external and / or middle ear alteration were excluded. The SND assessment was performed using bisyllables, one intonational group sentences (OIGS) and consonants in vowel context (VCV) from the BEPPA Battery. They were recorded in a CINTRA soundproof chamber, by a professional female speaker and masked using noise with a speech-like spectrum. The signals were reproduced by a digital audiometer. Verbal stimuli were presented at 60dB in diotic form, varying the noise level.The evaluations were carried out under the following conditions: no noise, with noise to signal-to-noise ratio (SNR) of 5dB, 0dB and -5dB. Wilcoxon Test was applied to compare intelligibility in the different conditions. There was no conflict of interest. The work was approved by the ethics committee of the Hospital Nacional de Clinicas.
It was observed that the discrimination percentages decreased as the SNR decreased for the three types of stimuli. In bisyllables and OIGS, significant differences (p <0.05) were observed for all SNR conditions. In VCV, significant differences were observed between SNR 5, 0 and -5dB, but not between the condition without noise and SNR 5dB (p> 0.05). In SNR -5dB OIGS obtained the highest discrimination percentage with 70%, followed by VCV (55%) and bisyllables (37%). In conclusion, results showed that the SND in this group of normal listeners is evidenced mainly from a SNR -5dB, and that the noise used hinders to a greater extent the discrimination of bisyllables and to a lesser extent the discrimination of OIGS. It is necessary to continue with research on this topic to promote the inclusion of SND evaluation in the audiological clinic of our region.

Resumen: La dificultad de discriminación del habla en ruido (DHR) es un síntoma auditivo frecuente, en personas hipoacúsicas y en sujetos con audición dentro de parámetros normales. Sin embargo, en nuestra región es explorada sólo en sujetos con prótesis auditivas. El objetivo fue describir la DHR de jóvenes universitarios con audición normal de Córdoba en los años 2020 y 2021. Se realizó un estudio descriptivo correlacional transversal. Participaron 33 estudiantes de edades comprendidas entre 20 y 30 años con audiometría normal. Quedaron excluidos quienes presentaron alteración de oído externo y/o medio. Para evaluar la DHR se utilizaron bisílabos, oraciones de un grupo entonativo (OUGE) y consonantes en contexto vocálico (CCV) de la Batería BEPPA. Se grabaron en una cámara insonorizada del CINTRA, por una locutora profesional y se enmascararon empleando ruido con espectro similar al habla. Las señales fueron reproducidas mediante un audiómetro digital de forma binaural diótica, presentando los estímulos verbales a 60dB y variando el nivel de ruido. Las evaluaciones se realizaron en las siguientes condiciones: sin ruido, con ruido a relación señal ruido (RSR) de 5dB, 0dB y -5dB. Se utilizó Test Wilcoxon para comparar la discriminación en las distintas condiciones. No hubo conflicto de intereses. El trabajo fue aprobado por el comité de ética del Hospital Nacional de Clínicas. Se observó para los tres tipos de estímulos que los porcentajes de discriminación disminuían a medida que lo hacía la RSR. En bisílabos y OUGE se observaron diferencias significativas (p<0,05) para todas las condiciones de RSR. En CCV se observaron diferencias significativas entre RSR 5, 0 y -5dB, pero no entre condición sin ruido y RSR 5dB (p>0,05). En RSR -5 OUGE obtuvo el mayor porcentaje de discriminación con 70%, seguido de CCV (55%) y bisílabos (37%). Se concluye que la DHR en este grupo de normooyentes se ve principalmente afectada a una RSR -5dB, y que el ruido utilizado dificulta en mayor medida la discriminación de bisílabos y en menor medida la discriminación de OUGE. Es necesario continuar con investigaciones en esta temática para favorecer la inclusión de la DHR en la clínica audiológica de nuestra región. . Universidad Nacional Córdoba.
